SPECIFICATION forming part of Letters Patent No. 725,694, dated April 21, 1903. 7 Application filed November 29,1902. Serial No. 133,304. (No model.) I

To ail whom it may concern-.-

Be it known that 1, CHARLES A. FORSBERG, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Fence-Making Machines, of which the following is a specification.

The object of this invention 'is to construct a fence-making machine in which the twisterheads are intermittently rotated by a toothed rack and a cam is employed to reciprocate the rack, in which the feeder and crimper wheels are intermittently rotated by the toothed rack and a crank-head having a link connection with the toothed rack, and in which an adjustable tension is employed t the line or lengthwise wires. 7 r

In the accompanying drawings, Figure 1 is a side elevation. Fig. 2 is a section on dotted line a, Fig. 6. Fig. 3 is a section on dotted line b, Fig. 2. Fig. 4is a section on dotted line 0, Fig. 5. Fig. 5 is a partial plan view. Fig. 6 is a side elevation of the mechanism for operating the feeding-rolls.

In the drawings 1 have only shown such parts of a fence-making machine necessary to an understanding of the location of my improvements thereto.

The main supporting-frame comprises the lengthwise beams 1, cross-beams 2, and vertical supports 3. The feed end of the machine has uprights 4, supporting a series of shafts 5, 6, 7, and 8. The shafts 5, 6, and 8 supportrollers 9, 10, and 11, respectively, and the shaft 7 is supported in boxes 12, which have an adjustable connection with the uprights 4, so as to locate the rollers 13, supported by the shaft 7, a proper distance from the rollers 10to give the required tension to the lengthwise wires 14, forming the fence, as it passes around the different sets of rollers above mentioned.

To the upper lengthwise beams are secured two supports 15, extending across the machine, and the inner faces of the supports are provided with lengthwise grooves which support a toothed rack 16 in a manner to permit it to reciprocate. These supports also support the twister-heads 17, and each twisterhead has a toothed pinion 18 connected therewith, and the series of pinions mesh with the toothed rack 16, and as the rack is reciprocated the pinions are reversibly rotated.

A slide 19 is supported by the cross-bars of the main frame and supports two rollers 20. The outer end of this bar hasia pivotal connection with an. arm 21 between its ends. The lower end of this arm has-a pivotal connectionwith a bracket 22, secured to the main frame, and its upper end has a circular enlargement 23, which is located ina corresponding recess formed on the outer end of the toothed rack 16.

A main driving-shaft 24 is supported by the main frame, and it supports two beveled gear-wheels 25 and 26. A shaft 27 is supported byv the main frame and has a beveled gear-wheel 28, meshing with the beveled gearwheel 25. The free end'of this shaft 27 supports a cam 29, which is located between the rollers 20, so that as the cam is rotatedit will impart a reciprocating movement to the slide 19, and through the arm 21 a reciprocating movement is imparted to the toothed rack 16. This cam 29, engaging the rollers 20, will move the slide positively in both directions.

A toothed rack 30 is supported by the main frame. A shaft 31 is supported by the main frame and has abeveled gear-wheel 32 meshing with-the beveled gear-wheel 26. The free end of this shaft supports a crank-head 33. A link 34 forms a connection between the crank-head and toothed rack 30 in order that cate the toothed rack 30. A frame composed ,of the bars 35 is supported by the mainframe.

This frame supports two standards which support two shafts 36 and 37. The shaft 36 supports a toothed wheel 38 and a feed-wheel 39, and the shaft 37 supports two toothed wheels 40 and41 and a feed-Wheel 42..v The toothed wheels 38 and 40 mesh together. Ashaft 43 is supported by the bars"35 and supports a toothed wheel 44, which meshes with the toothed wheel 41. To this shaft 43 is secured a ratchet-whee145, and on it are loosely mounted a toothed wheel 46 and disk '47, carrying a spring-actuated dog 48. As the rack reciprocates it will revolve the toothed wheel 46 and disk 47, carrying the dog 48. This dog will engage the notch in the ratchet-wheel and impart a rotary movement to the ratchetwheel and shaft 43, supporting it. This rotary movement of the shaft Will rotate the ratchet-wheel 45, and it in turn will rotate the toothed wheels 38, 4:1, and 4:4, and the rotary movement of the toothed wheel 41 will rotate the toothed wheels 38 and 40 and wire-guide Wheels 39 and 42. As the toothed rack moves in one direction the dog 48 will click over the ratchet-Wheel, which will allow the feed-wheels to stand still, and when moved in the other direction the feed-wheels will be rotated.

The operation of this machine so far as the manufacture of wire fence is concerned is the same as other machines-that is, the linewires are fed through the twister-heads, over the drum 49, and roller 50 to the reel. The wire forming the stays is fed in by the feedrollers 39 and 42, and the knife for cutting off the stays is not shown, as it forms no part of my invention. By means of the boxes 12 being adjustable the rollers 13 carried thereby can be moved toward and from the rollers 10 in order to vary the tension given to the line- Wires. The line-wires are drawn throughthe twister-heads by the rotation of the drum, and the means for imparting an intermittent rotary movement to the drum is not shown, such devices being old.

I claim as my invention- 1. In a Wire-fence-making machine, the

combination of the main f rame,twister-heads, a toothed rack for rotating the twister-heads, a link having a pivotal connection with the main frame and a pivotal connection with the toothed rack, a bar having a pivotal connection with the link, two rollers supported by the bar, and a cam engaging the rollers,thereby imparting a reciprocating movement to the toothed rack.

2. In a wire-fencemaking machine, the

combination of a main frame, two feed-roll-' feed-rollers.
